Turning an old router into wireless AP

I am trying to turn an old D-Link DIR-825 router into an access point. The D-Link is running dd-wrt firmware. I have the d-link set to AP, and DHCP turned off. I assigned it a local IP address of 192.168.1.2. Subnet at 255.255.255.0 . I have all the Wireless settings the same on both routers, and it seems to be handing off from one to the other flawlessly. However, when it switches to the d-link, I can't obtain an IP address on my phone. (which is what I am using to test the handoff). My question is, what should the Gateway and local DNS setting be set at in the d-link? Also, is that where the problem with obtaining an IP address is coming from?

Thanks!

That is the guide that I followed. But for some reason, it's still not working. The interconnect is from lan-lan. I can easily access the second router through any client connected to the primary router. As I walk from one end of the house to the other, the wifi signal obviously changes from one AP to the other, Once I'm on the secondary routers AP, I get no internet. When I try and click a link, it says no DNS, and then the wifi drops off and when the client tries to reconnect, it says unable to obtain IP address.

Any more ideas?

Edit - added pics of the router and WAP settings.

You didn't mention it in your description, so make sure that you have the DIR-825 connected to your main router using a LAN port on both routers. Do not use the WAN port on the DIR-825.

Also, try adding 192.168.1.1 as the Gateway and Local DNS on the DIR-825 (also try 8.8.4.4 for the DNS). Some routers don't need that info when acting as an access point, but it can't hurt to put them in and might resolve the problem.

Tried those settings, but no luck. Cable is connected LAN - LAN.
 
Can you get an ip address through dhcp if you plug in another device to the port that dd-wrt router is plugged into?

If you can get an ip address, the only thing i can think of would be dd-wrt router is not bridging the dhcpdiscover broadcast packet or any broadcast packet properly in between the radio and ethernet interface.

Try the simple stuff first by doing a hard reset on your dd-wrt router and checking the firmware to make sure it is compatible with your particular model. Here is the official guide from the dd-wrt:

https://www.dd-wrt.com/wiki/index.php/Wireless_Access_Point

If this still doesn't work, you can test the dd-wrt internal bridge's functionality by performing the following steps:

1. Manually configure a static ip address on your wireless device from the main router's dhcp pool
2. Connect to the dd-wrt ap's ssid
3. Once connected, do a simple ping to the main gateway.
4. If pingable, do a directed broadcast ping to 192.168.1.255 and see if you get a response from a device that's connected to the main router.
 
add one to the routers ip that corresponds with yours' example main router 192.168.0.1 wireless ap 192.168.0.2

turn off dhcp

plug in cable to lan port.

don't worry about dns or anything the main router will take care of all that.

enjoy.
